Application December 30, 1944, Serial No. 570,572

11 Claims.

This invention relates to the construction of a weighing scoop used for weighing materials, wherein the scoop is adapted for use especially in vthe handling of grain.

It is the object of my invention to provide several vimprovements over the construction shown Vin my Patent 1,913,296, issued June 6, 1933, and the prior art which came to my attention while the application of said patent was pending.

'The advantage of my present construction is that the spring Ais positioned on the scoop so that it will be substantially over the center of the load or weight carried by the scoop, whereby the `handle-the inner end of which is fastened to the outer end of the spring-is also positioned over the scoop for a considerable distance, thereby making it easier to handle and vshortening the entire structure with a resulting reduction in rweight and cost.

In my present method of mounting the spring, 'the height of `the structure is also reduced.

Another advantage is derived from my present method of mounting the downwardly extended lportion of the handle. The link members connecting this portion of the handle are attached to the closure end of the scoop in such a manner as to cover the pivots, thereby preventing grain or other material from getting onto the pivots and thereby affecting the operation of the structure.

A further advantage is derived from Athe fact that the spring is completely enclosed, and this :enclosure is Aprovided with stop means so that Athe spring cannot be injured 'by an overload.

Other andfurther advantages Iwill be discerned "from a study of the specification taken in connection with the annexed drawing, wherein:

' lFigure 1 is a plan view of `my improved type of weighing scoop, one portion of the handle being broken away to show the link members connect- 'ing it to the scoop.

'Figure 2 is a side view of the structure. Figur-e 3 is a view of Figure 2, looking from right to left, a certain portion being in section as indicated by the line 33.

Figure 4 `is a View on thev line 4-4 of 'Figure 1. Figure 5 is a View on the line 5-5 of Figure 4. In the various views, wherein like numbers refer "to corresponding parts, the weighing scoop is provided with a bottom l with side members 2 vand 3 and aclosure end 4. Extending from the closure end 4 forwardly between the side members I and 2, is a cover 5 which, as shown more particularly in Figures 3 and 5, has a depressed portion 6. Mounted on the median line of this depressed portion 6, is a spring 'I having one end fastened yto a stud 8 which passes through the portion E and is engaged by an adjusting nut 9, whereby the tension of the spring may be adjusted. The upper end of the spring is fastened Aby a stud IIJ, nut II and washer I2 to the inner end of a handle I3, the outer end of which has a downwardly extending portion I4 having oppositely disposed spaced ears I5 to which are pivotally mounted spaced link .members I6 and Il preferably made from a piece Yof sheet metal having downwardly extending sides I8 to embrace the ears I5 and being pivoted by pins I9 thereto.

The opposite ends of the link members I6 and Il have projections Y24 passing into slots 28 cut or formed into the web of channel-shaped members 2l and 22 that are fastened in any satisfactory Amanner as by rivets or spot-welding .to the closure end 4. The inwardly projecting ends 24 are pivoted by pins 23 to the channel-shaped members 2l and 22 and, as will be seen, these pivots are substantially covered to prevent grain or other material from getting onto the pivots and aiecting the operation of the scoop.

Preferably the handle I3 and its downwardly extending portion I4 is made all in one piece as may be done where sheet metal, such as steel or an alloy thereof, is used.

In order to protect the spring .'l from injury of any sort, I provide a cylindrical cover 25 therefor, the cover being clamped to the inner end of the handle I3 so as to move therewith. The spring stud 8 is positioned in a U-shaped bracket, one arm 26 of which serves as a support for a stud cn which a pointer 2l is mounted, the other end of the pivot stud being carried by a dial plate 28. As shown in the drawing, the dial plate is made in two pieces, but preferably it should be made in one piece and riveted or spot-welded to the side members 2 and 3 of the scoop; or it may be formed as a part of the cover 5. The upper end ofthe dial plate 28 is provided with a scale 29 that is calibrated in pounds and fractions thereof. The pointer 21 is connected by an arm 3'0 to a link 3I which is preferably integral with the arm 33. The upper end of the link 3l is fastened to a lug 32 preferably integral with the handle I3.

'The other arm 33 of the U-shaped bracket is provided with a vslot 34 to receive a linger 35 that is fastened -to or formed integral with and projects from the spring cover 25f The length of the slot 34 is such as to stop the extension of the spring and movement of the pointer directly after the full length of the scale has been covered by the pointer, thereby protecting the spring from an undue strain.

By having the spring positioned in the depressed portion 6 of the cover 5, the height of the structure is materially reduced and, furthermore, the spring is positioned so as to be substantially over the center of gravity of the load carried by the scoop; and since the handle extends over the cover portion of the scoop, the Scoop with its load is much more easily handled than in the structure ofmypatent previously yreferred to, wherein the handle is out beyond the end of the scoop.

FromY the preceding description, it should be evident that I have provided a weighing scoop that has many advantages over prior-art constructions.

What I claim is:

1. A weighing scoop including a channelshaped body having a closure end, a pair of channel members fastened to the closure end in spaced relation, each channel member having openings in their webs at their opposite ends, spaced link members having ends extending through said web openings .into the channels and pivotally anchored thereto, a handle having an extension at one end extending downwardly, this end having inwardly projecting ears pivotally connected to the ends of said link members opposite to the ends entering said channel members, a cover extending from the closure end over a substantial part of the scoop body, a dial plate carrying a dial or scale extending upwardly'from the body at the inner edge of the cover, a vertically disposed coil spring fastened a-t one end to the cover closely adjacent the dial plate, the opposite end of the spring being fastened to the free end of the handle, and being the sole connecting means between the scoop and the free end of the handle a pointer pivotally mounted closely adjacent the spring and extending in cooperative relation with the dial or scale, and link means connected between the pointer and the junction of the spring and handle.
